Hi all, I recently acquired the below fossil, a pair of articulated jaws, purportedly from Pachystropheus rhaeticus, still with teeth, found at Garden Cliff/Westbury-on-Severn. Whether I wasn't paying proper attention when I bought it or just hoping there wouldn't be any pyrite on the piece, when I received the specimen it turned out that there are quite numerous pyrite-crystals growing to the side of the fossil. As it's quite an unusual piece that I'd rather like to keep, I'm now looking for people with experience with pyrite from the Garden Cliff location. In essence, I'd like to ask how stable the pyrite from this location typically is: whether it decays into a black oxidation product or starts blooming with time. How concerned should I be about the stability of this piece? The pyrite itself looks relatively clean right now, so I'm thinking the rock on which the fossil sits hadn't been exposed for too long. But any advice would be welcome. @Welsh Wizard @Pterygotus @DanJeavs

I tried posting something up a few days back but got no reply - I think maybe i made the mistake of posting too much up at once. Well I have now done some minor prep on this chunk of Rhaetic bone bed from Aust Cliff, anyway, and on revealing more of the bone and consulting my new purchase of 'Fossils of the Rhaetian Penarth Group', my confidence in my original conclusion has increased - that this most prominent bone fragment is the end of a Pachystropheus rhaeticus femur or tibia. I guess I was hoping that someone here with a lot more knowledge of these rocks would be able to confim my hunch so I can feel happy labelling it as such! I want to go back there now...(for reference, bone piece is approx 2.5cm long)

I wanted to very briefly share something really pretty awesome. Some folks here know that in addition to Fossils on Wheels, I also work for the Gateway Science Museum. It’s a small children’s science museum and our fall exhibit is going to be about fossils. We are part of CSU Chico and the Geology Department is using our facilities to do some preparation work on a few fossils for the exhibit. I took some pictures of one awesome specimen. The table in the center of the frame contains multiple pieces of a Shastasaurus. It is a remarkable and scientifically important specimen. It was found near Shasta Lake and it’s Triassic. Close to complete and containing something special that I can’t really elaborate on. All of those bundles are ribs and verts. The second picture is a close up of one slab. I got to pick it up and it is really quite heavy but not everybody gets to hug a Shastasaurus so totally worth it lol In the far right of the picture, you can see the edge of a table and on that table is a partial Mastodon jaw includes a complete tusk though in two pieces. I’ll take pictures of that and a baby whale piece next time I’m at work. My desk is to the left of the whiteboard you see in the frame. My workspace has been taken over by large fossil critters !

Hi all, I visited Aust Cliff in South Gloucestershire, UK for a couple of hours last week. I wasn't expecting much as I know how heavily collected it is, but got a few bits of interest which I was happy with under the circumstances. I'd be interested in educated takes on a couple of bits of bone bed I found there at least, especially this first piece that contains what I believe to be multiple bone fragments as well as coprolite pieces and lots of small black fragments - not sure if scales, teeth or what. Here's a view showing what I imagine is one end of a reptile limb bone - could this be Pachystropheus? And on the other side are a couple of embedded chunks that have the honeycomb texture of bone but without the outer coating (not sure of the technical terms here!) No chance of identifying such things I presume, beyond 'yes it's bone'?

I got many bags of micromatrix to sift through over the Summer, one of them being from the Bull Canyon Formation, which is Late Triassic in age (~227-208.5 Ma). As has been said many times before, not much is known about the teeth that can be found here, unfortunately. The vast majority of fossils that I've found so far are fish scales, lots of fish scales. I've found a few teeth, serrated and non-serrated (mostly partial), a couple of tooth plates/jaw fragments, and random chunks of bone. The matrix is about medium grain size. For scale, the sorting dish I'm using has 1 cm squares. Most of the rock is a red color, and the fossils are almost entirely white. Here are couple of "in situ" shots: Jaw section (fish?): Tooth plate (also fish?): Serrated tooth fragment: Non-serrated, striated tooth fragment (amphibian?): A nearly complete serrated tooth!:

Greetings, After using this forum as a source of information for the last few years I have finally decided to create an account and return the favor. In the future when time permits and my new member status has passed. I plan to upload pictures of already identified fossils to my personal gallery in an effort to help others in their quest for answers. My main interests are vertebrate fossils, with a focus on amphibians, reptiles, fish, and early mammals. The Permian period is by far my favorite time period but I also love the Triassic. If I'm not out collecting and locating Permian fossil sites then I enjoy spending my time researching scientific papers and learning as much as I can about ancient wildlife. I'm not a gamer and I rarely watch tv or movies unless it's a documentary or lecture regarding something I'm interested in.

Hi, I found this bone at Aust cliff (late Triassic), I know that most bones from Aust are likely Plesiosaur or Ichthyosaur, but are often unidentifiable. Is it possible to identify this bone? It seems to have split around the back, so could probably be only half of the bone, and it looks to be the end of a bone. I've ordered a book on Rhaetian fossils, so hopefully that will make things easier. It measures about 8 cm across. Unfortunately I do not have anything with me to prepare it. Many thanks.

Been finding a few of these types of tracks recently. Will be curious to see if they actually are tridactyl dinosaurs.

Hello everyone! I was out at one of my Triassic track areas in New Jersey and came up with something non track-related I found interesting. We have all kinds of ripple marks, plants, etc. so I'm really not sure what this is.. can anyone help? Thanks!

Hi all, after seeing all these nice collections from other members I also want to share the collection of my father and I with you. The collections is of various time periods and sites. We started collecting in 2009 close to home in a quarry nearby Maastricht called 't Rooth (sadly this quarry is close for visitors since 2016). From there on we started visiting other quarries and the collection started too grew massively. We frequently visited the ENCI, Winterswijk and Solnhofen. I will start off with some of the display cabinets

Hi, i went on a trip to my new triassic spot and found something which reminds some sort of a rib trace on a marine bed. Look at the bottom of a rock Found near Chorzów, lesser Poland. Can you tell me what's that?
-
Second picture is what appears to be a tridactyl track. First picture might be also. According to the paleontologist there is discussion of the possibility of dinosaurs being around in this time period.

Petrified Wood from Triassic of southeastern Pennsylvania
traveltip1 posted a topic in Member Collections
This display contains 100+ specimens of the best petrified wood that I found, during more than a decade of fossil-hunting, in the Triassic age Newark Basin of southeastern Pennsylvania. The material is scarce. I have plenty more smaller pieces. The shelves dimensions are 6 feet x 5 feet x 1 foot.- 4 replies

Been digging my new area. Finding large area with what seems to be deep mud. Lots of partial, poorly impressed tracks so far. From the exploratory holes I’ve dug the area seems to cover at least an acre so hoping to find some good things.

Found this today. Rock is about 12-14” long. Paleontologist thinks it looks organic but doesn’t know what it is offhand. I’m thinking fossil unicorn, but I could be mistaken. Anyone?
